Normal duplication

LTO 2 : 200 GiB * 2 = 400 GiB

LTO 3 : 400 GiB * 2 = 800 GiB

Note that the factor 2 is used because 2 is the assumed compression ratio of the tape drives. If the compression ratio is different, the factor must be changed appropriately.

For information on how to extend FSE disk buffer with additional file systems or volumes, see chapter ”Monitoring and maintaining FSE”, section ”Extending storage space of FSE disk buffer” on

page 176.

•The target medium should not contain any valid data or header such as a tar archive label or an ECMA / ANSI label.

•The target medium should not be initialized.

•The target medium should not belong to any FSE media pool that is already assigned to an FSE partition.

When all duplication prerequisites are met, and the original and target media are prepared, you can make a duplicate of the original medium using the following command:

fsemedium --duplicate SourceBarcode TargetBarcode [--no-monitor]

If you do not want to monitor the medium duplication progress, specify the --no-monitoroption as shown in the command syntax above. Otherwise, the duplication progress will be reported to the standard output.

Forced duplication

When any of the last three duplication prerequisites is not met and normal duplication fails, you can still duplicate to the target medium if you use forced duplication functionality. You can perform a forced medium duplication using the following command:

fsemedium --duplicate SourceBarcode TargetBarcode [--no-monitor] --force

CAUTION: Since forced duplication overwrites any data that is stored on the target medium, data loss may occur on the target medium.

Example output for a medium duplication with enabled monitoring, using single tape drive

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
